The Projectile loom and the general shuttle loom in the different weft insertion, beating and weaving three parts. Weft induction by the Sheng box, twisted-axle shuttle mechanism, guided shuttle rail, shuttle box and shuttle shuttle conveyor and other components. Each loom has a number of loops only, the order from the loom for the weft weft into the shed. The power of the shuttle is derived from the elastic energy stored in the torsion axis, and the residual energy is absorbed by the hydraulic shock absorber. The shuttle is moving along the guide rail. It enters the shuttle box is braked, by the shed below the conveyor body back to the original place. Beat the use of conjugate cam mechanism. When the sley is advanced, the shuttle rails are moved into the shed, and the shuttle loops advance along the shuttle rails, and the weft yarns are introduced into the shed. In the shuttle loom on the application of folding, twisted and intermediate weaving device, woven single, double or multiple fabrics. When the synthetic fiber fabric is knitted, the edge warp is fixed with a fusing device.
